Dantech 12V 4A DC steel cased power supply with integrated ups

  • Single 4A 12V DC fused output

  • Integrated UPS battery back-up function

  • Mild steel powder-coated enclosures

  • Includes a spares-bag mounting kit

  • Input 230V AC @ 50Hz (+/- 10%)

This simple range of multi-purpose metal-cased power supplies provides 4A of 13.7V DC via individually fused outputs, for 12V DC equipment. The enclosure can also house a 7Ah VRLA battery, which the power supply will automatically charge while mains power is present, and use in the event of a mains power loss.

Manufactured and tested in Britain, this range of power supplies has a five-year warranty, allowing installers to fit and forget. It is ideal for where high reliability is required and where companies may have long service or maintenance contracts. Typical uses include powering door access controllers, electronic door releases, magnetic locks and CCTV cameras.

Integrated UPS battery back-up function

A 7Ah VRLA battery can be placed in the mild steel enclosure and connected to the battery terminals of the PCB. This power supply will automatically float-charge the battery to capacity, providing continuous uninterrupted power from the battery if mains power is unavailable.

Batteries are not included. This unit can be used with or without batteries fitted.

Mild steel powder-coated enclosures

Precision-made from mild steel and powder-coated white for an easy-clean, durable finish, this enclosure is ideal for wall mounting. The enclosure includes 'knock-outs' for cable gland entries.

Includes a spares-bag mounting kit

Each unit includes a spares-bag for the installation engineer. This kit contains useful items, such as cable glands, wall plugs and fixing screws.

Input 230V AC @ 50Hz (+/- 10%)

Designed to operate on UK standard mains power, this unit will accept a mains-powered input of 230V AC @ 50Hz (+/- 10%)
